To all whom it 'may concern:

Be it known that l, STEWART Dickson, a subject of the King of Great Britain, but having declared my intention of becoming a citizen of the United States, and residing in Upper Montclair, in the county ot Essex and State ot New Jersey, have invented certain new and useful improvements in Packingr for Aacetylene-Gas Tanks, of which the followingr is a specification.

The principal object of the present iuvcn` tionis to provide a packinpr or lilliug tor an acetylene tank which shall completelyv lill the tank and at the same time possess in* creased porosity or number of voids and which shall be sutllciently supported for preventing settling or consolidation and consequent creation of undesirable spaces ot conside 'able size, and which possessed ot these qualities and properties shall withstand the heat incident to Welding on the head of the tank after the packing has been put into it.

Aanother obliect of the invention is to prevent 'particles of the packing from accidentally passing oil with the gas.

The invention will be claimed at'the end hereolt, but will first be described in connection with the particular embodiment ot' it selected from among; various embodiments of it. for illustration in the accompanying drawings, in Which- Figure l, is a transverse sectional View illustrating' a packing or filling embodying features 01"' the invention and arranged in an acetylene tank. Fig. 2, is a transverse sectional View of Fig. l, and Fig. 3, is a pen spective view illustrating one section ot' the packing and containing dotted lines hereinafter referred to.

In the drawings 1, is an acetylene tank, the shape and size ot which may be varied. lt is completely filled with the packing,r or

`filling `which 'is shown as cylindrical with one tint end and one partly spherical or convex end. The packing is made up ot' sections Q, which arc duplicates of cach other and of which three arc `shown. although the number may be increased or diminished. These sections Q, when tittcd together, con-- stitute in ctl'cct a solid body. Each section 2 throughout a portion of its lcngtlu'toi' example between its cud il and thc dotted line 4, consists ot a mixture ot cotton and asbestos'liber, which is in consistency somothing like cotton batting and is thcrct'ore eit'tremely porous. From the end 5 to the i dotted line or in other Words, throughout a part ot' its length, each section consists of asbestos tiber referably pure' long' fiber asbestos, and tris is also porous. i

sists ot 12%, by Weight, of cotton and 88%, by Weight. of asbestos. The mixture of cotton and asbestos extends only far enough to be unaffected by the heat incident to Welding on the end of the tank and the parts of the packing exposed to the heat consist of the pure asbestos liber. Merely by way of illustration it may be said that in' a tank 18 long, the pure tiber extends forfl", but of course this is subject to Variation with the size of the tank and the amount of heat used, rl`he surface of each section constitutes a hard, strong wall that serves to support and give strength to it.

B v makingtbe filling or packing in a number of sections the number ot' these hard supporting walls is increased and there is theretore no extended cross-section of fibrous material. in this way the i'ibrous material is prevented troni settling, which is desirable, because ir it settled it would leave spaces that would be objectionable. The settling or undesirable packing of the liber may be brought about in many Ways, but the jar .ot' au automobile., on which these tanks are where the tank is simply filled with a nonsectional packing; whereas in the case of a sectional packing the multiplicity of Walls serve to prevent packing ot the fibrous material. t one end of the packing, where the gas is drawn oft', a layer of asbestos cloth 6 may be zulvautageously applied and it serves as a strainer to prevent any loose particles of the packing going out of the tank Ywith the gas,

The walls or exterior surface of each of the sections may be made hard and strong cate ot soda, which forms a hard, tough, strong;l skin. inasmuch as the sections are coxupui'ativcly small and the strong surface skin ot each serves to support its fibrous contents, it follows thaty the latter need not be packed hard because there is comparatively littleI of it in each section and in this way the porosity of the packing, as a Whole, can be increased.

What l claim is:

1. A packing or filling for 'acetylene gas tanks comprising sections' adapted to be suit-A able mixture for one end of the section con` largely used, is found to be sutticient in cases' b v treating them with a solution, as of sil1.`

fitted together to till the tank and each having a hard, strong skin and consist-ing throughout a portion of its length of a mixture of asbestos and cotton hber and 5 throughout the rest of its length of asbestos fiber, substantially as described.

2. A packing or filling for acetylene gas tanks consisting throughout a portion of its length of a mixture of cotton and asbestos 10 ber and throughout the rest of its length with asbestos fiber which resist heat incident to welding the tank, substantially as described.

In testimony whereof I have hereunto signed my name. Y
